PHP - Determine Which $_post(s) Has Values

I'm trying firstly to output hidden fields based on the values of the $_POST variable.

Then after that I want to output the values again in a unordered list.

I'm using the following code:
while (list($key, $val) = each($_POST)) {
if ($key != 'Submit') {
echo '<input type="hidden" name="' . $key . '" value="' . $val . '" />';
}
}

echo '<ul>';
while (list($key, $val) = each($_POST)) {
if ($key != 'Submit') {
echo '<li><strong>' . $key . '</strong>: <span class="highlight-219ddb">' . $val . '</span></li>';
}
}
echo '</ul>';

However the <ul> appears to be blank? Can I only use the list() function once on a particular variable?

Hello everyone,

I'm trying to code a section of the site which is like an advertising website (i.e, gumtree) where people can post an Ad on the site and have any responses sent to them via email. The thing is that I have a form where they can enter their details and need to POST the information to the following page which is a preview page of their Ad. I have the form action returning to the same page for validation but I need the $_POST vaules to populate the following page without sending information to the database (in an effort to keep the database clean should they decide not to publish their Ad.

There are 3 pages in total CREATE AD > PREVIEW AD (where they can go back and edit if they need to) > Publish AD (where they confirm terms and send to database).  I do have session variables already set after login in and a seperate table to hold the details after they have confirmed the Ad & terms.

Any ideas would be greatly appreciated.

Thanks, L-plate

Hi all,

I'm looking for some pointers in regards to my form..

How would  I firstly trim the $_POST value of the variables that come through via the form (I'm only using one for now)..I know I'm making a right dogs dinner of it. 

In my head I'm thinking, trim all the posts first before i even assign a variable to it ( i dont know if thats possible), then use an array for when more values start coming through via the form. You know as i make a contact form that requires more data from the user..

 

<?php
require_once '../connection/dbconfig.php';

include_once('../connection/connectionz.php');
//get the values



//Get the request method from the $_SERVER
$requestType = $_SERVER['REQUEST_METHOD'];
//this is what type
//echo $requestType ;

if($requestType == 'POST') {
	
	//now trim all $_POSTS
	$search_products = trim($_POST['search_products']);

	//
	if(empty($search_products)){
		echo '<h4>You must type a word to search!</h4>';
	}else{
		$make = '<h4>No match found!</h4>';
		
		$new_search_products = "%" . $search_products . "%";

		$sql = "SELECT * FROM product WHERE name LIKE ?";
		//prepared statement
		$stmt = mysqli_stmt_init($conDB);
		//prepare prepared statements
		if(!mysqli_stmt_prepare($stmt,$sql)) {
			echo "SQL Statement failed";
		}else{

			//bind parameters to the placeholder
			mysqli_stmt_bind_param($stmt, "s", $new_search_products );
			mysqli_stmt_execute($stmt);

			$result = mysqli_stmt_get_result($stmt);
			echo'<h2> Search Result</h2>';
			
			echo 'You searched for <strong><em>'. $search_products.'</em></strong>';
			while($row = mysqli_fetch_assoc($result)){
			echo '<h4> (ID						: '.$row['pid'];
			echo ') Book Title						: '.$row['name'];
			echo '</h4>';
		}
	}

}
	}
;?>

 

If any one can shed some light on this, or some pointers..that would be very nice...

Thanks

Darren

Hi,


I have set up 2 php pages

page 1 - add_entry2.php
In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php
In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1

Now the problem starts here
on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it.

One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1. 


I am able to retain values if I use the code Code: [Select]
<form action="add_entry2.php" name="eval_edit" method="post" format="html">
i,e if I submit back to the same page and retrieve values form $_POST


but If I use the code Code: [Select]
<input type="button" value="Back" onClick="history.go(-1);return true;">to get back to add_entry2.ph it looses all the values. Is there any other way to code the BACK link retaining my $_POST values(Do you think $_SESSION would work in this case?)

All,
I have a zip code and for example the zip code is 01101. How can I determine if the first character in this is a zero?

Thanks in advance.

I am pulling records from a mysql db.   

Example Output:

Team A=  Our Team
Team b = An opponent team
Team A score = 7
Team B score = 8

Team A = Our Team
Team b = Another Opponent
Team A score = 3
Team B score = 1


What I need now is to add ONE more output, which is whether this is a "WIN" or a "LOSS".

Should I add a field into the table that calc's this?    If so, how?   Please be specific.

Or, should I use php to compare Team A score vs Team B score PER every record and then insert this new variable into the output.    If so, how do I create a new variable value for every single output in the table?


I know ultimately that this is a IF THEN type of calc, but can't quite figure out how specifically.   

Please be specific.

Thanks

My uploader allows the following file formats:

jpg
pdf
gif
png

I tested that if someone was to name a file configure.php.jpg, my uploader allows it to upload

I want to do a check to see if the user has 2 extensions, and if so it will not allow them to upload.

I was thinking of just checking if the file name has two "." (dots) in the name. What function could I use to do this?

Or .. is there a better way?

This may sound funny, but I'm not sure what I was trying to get this code to do...
Code: [Select]
        <!-- Find Current Page Name -->
        <?php
          $page = basename($_SERVER['REQUEST_URI']);
echo '<p>$page = ' . $page . '</p>';
//          if ($page == '') {
          if (($page == '/')||($page == '')||($page == 'index.php')){
            $page = "index.php";
echo '<p>You are on the Home Page.</p>';
          }else{
echo '<p>You are on Some Other Page.</p>';
}

What I mean by that is I'm not understanding why I chose...
Code: [Select]
          if ($page == '') {

and then...
Code: [Select]
          if (($page == '/')||($page == '')){

and then...
Code: [Select]
          if (($page == '/')||($page == '')||($page == 'index.php')){


Why would I get those different results from basename($_SERVER['REQUEST_URI'])??

And what should I expect locally on my Laptop with a Virtual Host set up (e.g. "http://local.debbie/index.php") versus using a Test Site (e.g. "http://www.doubledee.byethost2.com/") versus a real site (e.g. "www.debbie.com")?!

Hope I'm making some sense here...

Am currently using this code, and actually thinking about it should split the query to an include in order to allow for other database drivers, on the chance we may decide to ditch the old MySQL. But I digress from the question.

Code: [Select]
include($lib."dbconfig.php");

$q = 'SELECT * FROM file WHERE this = "'.$that'";
$result = mysql_query($q);

if (mysql_num_rows($result) > 0)

If the query doesn't pick up a row I'm getting this error yo,

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in D:\webpages\*\*\admin.php on line 553

So what would be a better way of testing if the query was successful? 

I have this function, but it doesnt work. Basically the list outputs a list of news features, and puts a line under neath each article to seperate them. However once the last article has been reached, I don't want the break to be shown.

this is my code, any help would be appreciated as i am really struggling on this. Just need to determine the last item in the array, and stop the <hr split> from being output.
function newsFeature(){
$event = "SELECT imgname, title, content, pkID from news ORDER BY date, time DESC LIMIT 5";
$event_page = query($event);
$count = numRows($event_page);

while ($row = mysql_fetch_assoc($event_page))
{
$rowcount = $count;
$para = substr($row['content'] , 0,100);
$result .= '<article>';
$result .= '<a href="news-article.php?pkID=' . $row['pkID'] . '"><img src="uploads/thumbs/' . $row['imgname'] . '" alt="" width=116 height=83/ ></a>';
$result .= '<h2><a href="news-article.php?pkID=' . $row['pkID'] . '">' . $row['title'] . '</a></h2>';
$result .= '<p>' . $para . '...</p>';
$result .= '<p><a class="read-more" href="news-article.php?pkID=' . $row['pkID'] . '">Read more<span></span></a></p>';
$result .= '</article>';
if($row != end($row[])){
$result .= '<hr class="split">';
}
}
return $result;
}

I can determine which radio button is selected for each file upload prompt because I have a name and a value. So the array name=image can have one of three values for each file upload prompt.

Is there a way to determine which of the three file upload prompts was loaded (clicking browse & select image) with an image and which was not? There doesn't seem to be a value like there is with radio buttons. I want to be able to replace an already uploaded image with another.

Thanks.

<input type='radio' name='image[image0]' value='keep' checked='checked'/>
<input type='radio' name='image[image0]' value='delete' />
<input type='radio' name='image[image0]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image1]' value='keep' checked='checked'/>
<input type='radio' name='image[image1]' value='delete' />
<input type='radio' name='image[image1]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image2]' value='keep' checked='checked'/>
<input type='radio' name='image[image2]' value='delete' />
<input type='radio' name='image[image2]' value='replace' />
<input type="file" name="image[]" />

if (isset($_POST['submitted']) && 
($image = $_POST['image'])) {

foreach($image as $imageKey => $imageValue) {
if ($imageValue == 'keep') {
do this
}
}
}

Hi,

Competitors vs. against each other and are recorded in a database. Each participant equally has 4 matches each, as you can see in the attatchment following the points gained in their played matches. I want to be able to determine the qualified participants according to either their "points" or "wins/losses". If two competitors have the same points, then I have already made a solution that another match must be generated for the two participants with the same points and draws can not be submitted which means the points will always be different for each team.

I want to pick out half of participants 8/16 (screenshot below) with highest points which will be the qualifiers, or pick out half participants 8/16 with best match stats according to wins/losses.

Any help I would be very grateful, thanks.
